Product FAQs
7 answersWhat does the A suffix in the QF115A catalog number indicate?
It indicates the inclusion of an automatic self-test feature. This mechanism routinely tests the internal GFCI circuitry to confirm proper function, complying with updated UL 943 requirements.
What is the ground fault trip sensitivity for this breaker?
The QF115A provides Class A personnel protection. It is calibrated to trip when it detects a ground fault leakage current of 5mA.
How is the pigtail neutral wired during installation?
The circuit load neutral must connect directly to the load neutral lug on the breaker. The factory-installed white pigtail wire is then routed and landed directly on the panel neutral bus bar.
Can the QF115A replace a discontinued QF115 breaker?
Yes. The QF115A is the direct upgrade and exact replacement for the older QF115 model. It shares the same plug-on footprint while adding modern self-test functionality.
Does this breaker replace Murray 15A GFCI breakers?
Yes. Siemens phased out the Murray product line. The QF115A replaces discontinued Murray GFCI models like the MP115GF. Always confirm the panel label permits Siemens QP or QPF2 breaker types.
Which load centers are compatible with this GFCI breaker?
The QF115A is designed for plug-on installation in Siemens PL, ES, EQ, and Ultimate series load centers.
What protective trip functions does the QF115A provide?
It features thermal magnetic trip technology with LIG functions. This delivers a long time delay for thermal overloads, instantaneous response for short circuits, and ground fault protection.
